Description

[Detailed description of the invention] The present invention relates to a slide lever switch, and in particular, it is disposed within a case body having a terminal board on which a plurality of fixed terminals are arranged, and is switched in sliding contact with each of the fixed terminals. A slider consisting of a sliding part holding a movable contact piece, an operating part extending from one end surface in the sliding direction of the sliding part and having an engagement hole in a part thereof opening toward the inside of the case body, and the case. an actuating arm that is rotatably supported on the main body and has a bulge at its distal end that has a maximum cross-sectional dimension substantially equal to the engaging hole and is freely engaged with the engaging hole; an operating body having a more operable operating part, and transmits the rotation of the operating body to the slider through a freely connecting engagement between an engagement hole of the slider and an operating arm bulge of the operating body. This slide lever switch has elasticity in the engagement hole in which the operating arm bulge is engaged, so that even if the dimensions of the operating arm bulge and the engagement hole are slightly different, It is an object of the present invention to provide a slide lever switch that can preferably shift a slider to a predetermined position by absorbing errors and keeping the bulge and the engagement hole in tight contact at all times.

Conventionally, in this type of slide lever switch, the engagement hole is formed as a complete hole, and the hole size cannot be changed, and the operating arm bulge of the operating body is fitted into this hole. If the size of the operating arm bulge is larger than the hole size, the friction between them will increase, preventing smooth flexing action, giving a sense of uneasiness to the operator, or causing the slider to move in a straight line. The switch may not slide properly and may adversely affect the performance of the switch. On the other hand, if the dimensions of the operating arm bulge are much smaller than the hole dimensions, the gap between them will become large and the slider will move by the gap independently due to vibrations, etc., apart from the operating body, which will adversely affect switch performance. . Therefore, in the conventional slide lever switch of this type, it is troublesome that the setting of the dimensions of the bulging part of the operating arm and the dimensions of the hole, as well as the manufacturing thereof, require careful attention.

The present invention has been devised in view of the conventional problems, and will be described in detail below with reference to the drawings.

FIG. 1 is an external perspective view showing a slide lever switch according to the present invention, and FIG. 2 is an axial longitudinal cross-sectional view of the switch shown in FIG. 1.

Reference numeral 1 denotes an insulating terminal board on which a plurality of fixed ends 12 are arranged. The terminal board 1 is disposed on the lower surface of a case cover 2 having a U-shaped cross section. Form. Said case cover 2
are the upper wall plate part 2A, both side wall plate parts 2C, and the rear wall plate part 2D.
are integrally formed from a single sheet of thin iron material, and a front wall portion 2E is formed by bending a portion of both side wall plate portions 2C outward at approximately a right angle, and the front wall portion A mounting screw hole 4 is formed in 2E. The center of the mounting screw hole 4 is located substantially on the extension line of both side wall plate portions 2C. Engaging protrusions 2C ₁ , 2C ₂ , 2C ₃ are formed at the lower ends of the both side wall plate parts 2C, and the protrusions 2C ₂ are connected to the terminal board 1 disposed below the cover 2. The protruding pieces 2C 1 and 2C ₃ can be bent inward from the bottom to serve as engaging claws for fixing the terminal board ₁ to the cover 2.
are engagement claws that are inserted into the engagement holes of the printed circuit board (not shown) when the switch is attached to the printed circuit board (not shown), and the printed circuit board has stepped portions 2C ₁₁ and 2.
C ₃₁ is inserted until it makes contact.

Reference numeral 5 denotes a slider that is slidably disposed within the sliding hole 3A of the case body 3 along a row of fixed terminals 12 fixed to the terminal board 1; A sliding portion 5A holding a movable contact piece (not shown) that is switched into sliding contact with each of the fixed terminals 2 on the opposing surface side;
A is integrally molded with an actuating part 5B which extends from one end surface side in the sliding direction and has an engaging hole 5b opening toward the inside of the case main body, and the said engaging hole A notch 5b ₁ is formed in one side of 5b, and this notch 5b ₁ allows the actuating portion 5B to
The part _5b2 has elasticity and can be easily deformed, so that the size of the engagement hole 5b can be changed somewhat or greatly. Reference numeral 6 denotes an operating body that is rotatably supported via a collar 8 on a pivot 7 that is pivotally supported between both side wall plate portions 2C of the case cover 2; A lever portion 6A extending larger than 2E, and a bulging portion extending toward the actuating portion 5B side of the slider 5 and having a maximum cross-sectional dimension at its tip that is approximately equal to or slightly larger than the engagement hole 5b of the actuating portion 5B. an actuating arm 6B with 6B ₁ ;
A detent recess 6C and an escape recess 6D are provided on the same plane, and a curved stopper engagement elongated hole 6E is further provided. A fixed shaft 9 pivotally supported between both side wall plate portions 2C of the case cover 2 is inserted through the stopper engagement elongated hole 6E, and both ends of the stopper engagement elongated hole 6E are connected to the fixed shaft 9.
By coming into contact with the operating body 6, the rotation range of the operating body 6 is restricted. 10 is a daytent device case 10A fixed to the case cover 2.
and a coil spring 10B arranged in the storage hole 10a of the case 10A, and the coil spring 10B always keeps the daytent recess 6C of the operating body 6
This is a detent device formed by a ball 10C which forms a contact and is pressed into contact with the ball 10C.

The slide lever switch configured in this manner switches and stops the slider 5 between the position shown in FIG. 2A and the positions shown in FIGS. 2B and 2C using the daytent recess 6C and the daytent device 10. In particular, in the state shown in FIG. The mating elongated hole 5E and the fixed shaft 9 are set. The states shown in FIGS. 2A, B, and C can be switched to the detent type by operating the lever 6A and rotating the operating body 6.

As described above, the slide lever switch according to the present invention has a notch _5b1 provided on the side surface of the engagement hole of the slider actuating portion 5B to make the engagement hole portion elastic. Operating arm bulge 6 of operating body 6
b ₁ are designed to be freely connected and engaged, so even if the maximum dimension of the bulging portion 6b ₁ is made to be approximately equal to or slightly larger than that of the engagement hole 5b, the error will be absorbed by the engagement hole 5.
Since it is absorbed by the elasticity of b, manufacturing errors can be tolerated, and there is an effect that a close engagement between the engagement hole 5b and the operating arm bulge _6b1 can be obtained satisfactorily.
